Pertumbuhan Tomat pada Frekuensi Pengairan yang Berbeda

Abstract

<p>Tomato (Lycopersicum esculentum Mill) is one of horticulture commodities with high economic value and still need seriously handling especially for increasing fruits quality and quantity. However the production of tomato has not fullfilleed the demand yet. Therefore it is necessary to develop production. On lowland, the issue not only high temperature but also availability of water is unpredictable.This study aimed to investigate the effect of irrigation frequency on the growth of Mutiara, Opal, and Gondol tomato variety. This research was conducted at the Greenhouse Laboratory of the Agriculture Faculty, Sebelas Maret University with attitude 95 m asl. Implementation of the research conducted from January to May 2013. This research used completely randomized factorial design with two factors, namely variety of tomato (Gondol, Opal and Mutiara) and watering frequencies (everyday, once in 3 days, once in 6 days, and once in 9 days). The results showed that plant height, number of leaves and number of branches are influenced by the variety of tomato and irrigation frequency, whereas chorophyl content is influenced by the watering frequency. Growth component and chlorophyll content of tomato decreased with increasing irrigation frequency.</p>

Growth Response of Oval Red Cherry Tomatoes (Solanum lycopersicum Var. Cerasiforme) to Different Frequency of Watering

“…Salinity can improve the quality of tomatoes (Jumawati et al, 2014), caused by increased solute through the arrangement of osmotic potential. Salinity can also increase the antioxidant content in the fruit (Gautier et al, 2010).…”

“…Tomatoes are plants derived from the family Solanaceae susceptible to water shortages during infancy (Lestari; Jumawati et al, 2014). Drought events cause lack of water in plants.…”

“…Research Jumawati et al (2014) showed that the rarer the tomato plant (Lycopersicum esculentum Mill) watered causes low growth and physiological components, but the quality of the fruit increases. Another study conducted by Nurul (2015), also stated that drought checks affect the average height of the plant, the number of fruits, the diameter of the fruit and the chlorophyll content of tomato leaves (Lycopersicum esculentum Mill).…”

Respons dua generasi tomat mutan insensitif etilen Sletr1-2 terhadap cekaman kekeringan

“…Rendahnya nilai pertambahan tinggi tanaman tomat mutan Sletr1-2 dalam kondisi cekaman kekeringan diakibatkan oleh pertumbuhan daun (Tabel 2), dan akar yang terhambat (Tabel 3), sehingga tomat mutan Sletr1-2 terganggu kemampuan berfotosintesisnya. Jumawati et al (2014) Jumlah daun tomat mutan NIL Sletr1-2 dan BC3F1Sletr1-2 lebih sedikit dibandingkan dengan tomat Intan pada kondisi cekaman kekeringan. Hal tersebut disebabkan oleh pertumbuhan akar kedua tomat mutan yang terhambat (Tabel 3) dan akibat kematian sel yang terjadi pada bagian daun tanaman yang disebabkan oleh akumulasi ROS (Reactive Oxygen Species) pada jaringan tanaman (Poóret al, 2015).…”

Effects of Various Irrigation and Fertilizer on Water Efficiency and Tomato Yield (Solanum lycopersicum) in Alfisols

“…Irrigation influences many plant attributes of tomato, such as the height of the plant, the number of leaves, the number of branches, etc. Practicing irrigation less on tomatoes often reduces the growth and physiological components but increases fruit quality (Jumawati et al, 2014). Xiukang and Yingying (2016) reported that increasing irrigation level influenced the increase in tomato fruit yield, fertilizer rate, and decreased water use efficiency.…”
